MOUNTING FOR GOLDPIIEAE' Specification 01' Letters Patent.

Patented July 14, 1914.

Application tiled April 17,;1013. Boria1No.761.Bfi7.

' To all whom it may oonoem:

. readily handled and which may be used without the necessity of applying sizing to the leather or other material to which the le f is to be afiixed. Heretofore in aflix: ing gold leaf and other metal leaves to leather and other material it has become necessary to apply to th material a sizing and then overlay the sizing with a layer of metal leaf, after which the necessary characters are afiixed to the material by means paper such as is ordinarily used upon which to spread the sheet of metal foil 11. the preparation of the improved mounting a sheet of metal foil 11 is spr ad upon one of a heated die. By that method not only is the material disfigured by having the sizing aflixed thereto, but much time iscoIisume'd by the operator in doing this, and more time is consumed in removin the sur= lus leaf from the material after t e desired impression has been mode. Wh this metal leaf is gold the portion lost in its removal from t e sized material is of fi0ilsii= arable value. Where the ordinary oldleaf is applied to sized material great oars has to: be exercised to keep the metal layer fiat and free irom wrinkles. I

The present invention consists in provid= log a newarticle of manufacture that will overcome these bjections, said article consistin of a she t of gold leat with a back-- ing 0 nonadhesivetpadper applied ther t by pressure and provie on the opposite face thereof with a' fine coating of adhesive sislog.

The invention further consists in: certain Fig. 3 represents a sheet of lg. t represents, in diagram greatly enlarged, the'edges of a sheet-of pa per, a sheet of metal foil su erimposed thereon, and a sheet of prepare paper superimposed upon said metal f il. Fig. 5 represents a sheet of the pre ared paper vhaving a sheet of metal fail a. xed thereto by pressure, and showing in the upper left hand corner a coating of sizing applied thereto. Fig. 6 represents an enlarged re verse view of a portion of the sheet of repared paper having the metal fail a' xed thereto, andshowing its condition after a plurality of characters have been removed. therefrom by means of a heated die, and Fig, 7 represents a portion of a hook show- .ing thereon a metal leaf removed from said sheet of metal leaf and aflixed thereto.

plurality of characters inv Similar characters designate like arts throughout the several figures of the raw= 'ings.

In the drawings, 10 represents a sheet of of the sheets. Qfpaper 10 and then a sh et or previously prepared pa or 12 is superim posed thereon as indicate. in Fig. 4; of the drawings. This sheet of paper 12 is prefer ably treated to a paraflin bath so that it is trans arent. The three sheets arethon sub= and the sheets 10 are removed therefrom.

The whole face of the metal foil 11 and that ortion of the sheet of the paraflinpap r 12 exposed is treated to a spray of suitable siain material as shown at 13 in the. upper left and corner of Fig. 5 This sizing Ina" terial nay be at any suitable composition that will remain impervious to moisture and is adaptedto be brought intoa tacky condi= tion only when sub ected to intense heat.

metal leaf and also to other characters whichhave been previously removed therefrom. This application of the heated die will affect only that portion of the sizing directly op posite the characters upon the die and will cause that portion of the metal leaf to be firmly fixed to the leather or other material.

When this has been accomplished the sheet is removed from the material and all of the metal leaf upon the sheet of paraflin paper 12 will be removed therewith except that portion thereof which has been fixed to the material by the action of the heated die.

When the mounting has been used several times the appearance of the mounting will be similar to that indicated in Fig. 6 of the drawings, and the appearance of the leather or other material to which the metal leaf has been applied will be similar to that shown in Fig. 7 of the drawings with no disfigurement about the characters of sizing, such as is usually found when the characters have been applied in the usual manner.

It is obvious that by means of this mounting it is unnecessary to cut up the sheets of metal foil into small pieces as has been customary, and by this means much waste of material is obviated. Moreover,

sheet of paraffin paper, and" when the entire surface of the mounting has been utilized these sheets are accumulated and burnt and all the -metal leaf not used remains afiixed to the the metal remaining thereon is thereby saved and may be returned to the manufacturer to be formed into new sheets of metal foil.

The coating of sizing on the gold leaf is very thin and of only suflicient quantity to cause the gold to adhere to an article when a heated die is applied. As a consequence,

when the heated die is! applied and the sizing opposite the raised portions becomes tacky there is not'enough substance thereto to permit it to spread beyond the outlines of the characters on the die'and a much more perfect imprint is assured as a result.

Another advantage of this improved article of manufacture is that the workman is not bothered with keeping the leaf fiat as has been the case heretofore when no backing was provided for the sheet. Moreover, in the application of the gold leaf a great saving of time is assured by the use of the improved sheet.

It is believed that the many advantages of this improved article of manufacture will be fully understood from the foregoing description. 7

Having thus described my invention, I claim: I

1. As a new article of manufacture, a sheet of gold leaf having a backing of paper on one face and a coating of adhesive sizing applied directly to its other face.

2. As a new article of manufacture, a sheet of gold leaf having a backing of transparent paper on one face and a coating of adhesive sizing applied directly to its other face.

Signed by me at 4 Post Ofiice Square, Boston, Mass, this 12th day of April, 1913.
